The memory of my mother will always be a blessing to me.

The value of a good idea is in using it.

Genius? Nothing! Sticking to it is the genius! Any other bright-minded fellow can accomplish just as much if he will stick like hell and remember nothing that's any good works by itself. You've got to make the damn thing work!...I failed my way to success.

The three great essentials to achieve anything worth while are: Hard work, Stick-to-itiveness, and Common sense.

The biggest failure of man is that he gives up before he realizes how close he was to success.

A reporter called on Edison to interview him about a substitute for lead in the manufacture of storage batteries that the scientist was seeking. Edison informed the man that he had made 20,000 experiments but none had worked. "Aren't you discouraged by all this waste of effort?" the reporter asked. Edison: "Waste! There's nothing wasted. I have discovered 20,000 things that won't work."

The first requisite of success is the ability to apply your physical and mental energies to one problem without growing weary.
